The small, golden light pulsed warmly against William's palm, a tiny, triumphant beacon against the encroaching forest night. Success. After days of frustrating failure, he'd finally executed a spell. The feeling was… unexpectedly potent. He held the glowing stone aloft, admiring the soft radiance. It was admittedly weak, barely comparable to the emergency LED on a cheap keychain back home, but infinitely more satisfying than achieving 99.9% accuracy on any market simulation. Debugging flawed C++ libraries never produced this kind of visceral feedback loop. This was real, tangible energy responding to his will. He could still feel the faint echo of that inner warmth, the thrumming connection he'd briefly established. "Though," he conceded internally, a wry smile touching his lips, "a slightly higher success rate than 1-in-a-few-hundred would be statistically preferable moving forward. Less chance of accidentally summoning… well, best not to speculate."
His moment of self-congratulation was cut short as his gaze returned to the other light source, the reason he'd gotten to his feet. Across the small clearing, partially obscured by a thicket of ferns that shimmered strangely where the light touched them, was the anomaly. A faint, translucent sky-blue luminescence, pulsing with a slow, soft rhythm. It wasn't the focused point of his Light spell, nor the flickering heat of the campfire embers. This was larger, more diffuse, a softly glowing haze hovering just above the ground, its edges indistinct. Anomaly investigation protocol: Active.
Clutching his own golden light source like a talisman-turned-flashlight, William took a tentative step forward, the moving shadows cast by his hand making the familiar trees seem suddenly alien and menacing again. "Great," he thought. "Now that I can make my own light, the ambient darkness looks statistically more threatening. Excellent system design."
He moved closer, drawn by the same analytical curiosity that drove him to dissect complex datasets. The blue glow remained steady, pulsing gently. It emanated no discernible heat, unlike his own spell-light or the dying fire. As he got within arm's reach, the formlessness began to… resolve. Not into a shape, but into a pattern. Gradients of colour within the blue haze, paler regions fading into slightly brighter, more intense zones of cyan and near-white, arranged in complex, shifting clusters. Data visualization? The thought flickered, absurd.
Then, with the force of a system crash, recognition hit him. The pattern, the colour gradients mapping intensity… it was utterly, impossibly familiar. Here, in this world of primal fears and nascent magic, hovered the ghost of his previous life.
It was a goddamn heat map.
He stopped dead, staring, his mind struggling to reconcile the input with established reality parameters. Error: Cognitive dissonance level critical. He'd spent thousands of hours analysing displays just like this – market volatility, server load distribution, demographic clustering, coaxing insights from coloured blobs. But here? Glowing ethereally in mid-air, powered by… what exactly? Wishful thinking? "It's like finding a fully functional Wi-Fi hotspot broadcasting stock tickers in the dinosaur era," he muttered aloud, the words sounding thin in the quiet air. "What's next? A goblin V.P. presenting quarterly earnings via holographic PowerPoint?" This made zero logical sense.
Heat maps required data. They required sensors to collect that data. They required processing units and display technology. None of which, according to every observation he'd made so far, existed in Aver. Assumption: Local technological level approximates pre-industrial Earth, augmented by poorly understood magic system. Goblins were demonstrably not running statistical analysis packages. Yet… there it was. Shimmering, pulsing gently, undeniably a data visualization projected onto reality itself. Hypothesis 1: User experiencing complex, persistent hallucination triggered by stress, injury, and mana exposure. Hypothesis 2: Reality's underlying operating system includes integrated data visualization tools accessible via unknown mechanism. Hypothesis 2 currently violates known laws of physics, but Hypothesis 1 fails to account for consistent sensory input. He almost laughed. This is fine.
Hesitantly, he reached out a trembling hand, fingers brushing the edge of the translucent blue display. The sensation was bizarre. Not solid, yet not entirely intangible. It yielded like smoke, but with a faint, cool static tingle, a subtle resistance like charged air. He could feel a distinct coolness radiating from the paler blue areas, a subtle, almost imperceptible warmth from the brighter cyan zones near the center. Tactile confirmation of the visual data gradient. His brain felt like it was about to blue-screen. Logic error 404: Physical laws not found.
He forced himself to analyse it, pushing past the sheer impossibility. No labels, no axes, no scale, no legend. "Debugging uncommented legacy code all over again," he thought with a familiar stab of frustration. "Thanks, universe. Excellent documentation." But even without context, the structure was apparent. He could see the patterns, areas of high intensity clustered together, gradients showing rates of change, isolated hotspots. He could perceive the information, even if he couldn't yet decipher its meaning. What data was it representing? Ambient temperature? Magical energy fields? His own vital signs?
The implications slammed into him then, staggering in their potential. If this… interface… was somehow connected to him, to his magic… He thought back furiously to the past week of frustrating failure with the Light spell. The inability to understand why it wasn't working, what he was doing wrong. If he'd had this, a visual diagnostic, real-time feedback showing his mana flow, the accuracy of his runic visualization, the resonance of his incantation… he could have debugged the process! Identified the errors, corrected the parameters, iterated towards success! "Hours of painful trial-and-error," he realized with bitter clarity, "potentially bypassed with adequate system monitoring tools! This is why comprehensive QA and user feedback interfaces are critical!"
A surge of intense excitement, sharp and purely analytical, cut through his lingering fatigue and bewilderment. Data. This was data made manifest. He needed to understand it. What triggered it? What did it display? How was it generated? And crucially, could he control it? Interact with it? A visual interface to this world's underlying systems… the possibilities were exponential. A heat map, while a useful tool for relative intensity visualization, was functionally limited without context or controls. Requires API documentation. Or at least a tooltip.
As if responding to his focused thought, the translucent blue heat map shifted. The blobs of colour flowed and rearranged themselves smoothly, the gradients sharpening in some areas, fading in others. A new configuration snapped into place. Still undeniably a heat map, still unlabelled, but displaying a different dataset, or the same dataset from a different perspective. William stared, his mind racing, desperately trying to correlate the change with anything, his own thoughts, his position, the surrounding environment, the state of his Light spell still glowing faintly in his other hand. He felt like he was watching a high-frequency trading algorithm redraw its predictions second by second, trying to guess the underlying variables.
And then, something cold trickled down his spine. A connection sparked, an intuitive leap his logical mind hadn't explicitly made but now recognized with dawning, chilling certainty. The pattern… the focus of the heat map… the way it seemed cantered vaguely on him…
"Is this…?" The thought was incomplete, cut off by a wave of vertigo. "Is it mapping… me? My mana? My… system state?"
A bone-chilling shiver traced its way across his skin, unrelated to the night air.
